SNOW-PLOW,

SPECIFICATION forming part of Letters Patent No. 250,164, dated November29, 1881. I Application tiled October 5,1881. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM W. OSBORNE, of Kansas City, in the county ofJackson and State of Missouri, have invented a new and usefulImprovement in Snow-Flows, of which the following is a full, clear, andexact description.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a sectional side elevation of my improvement. Fig. 2 is aside elevation of the same, part being broken away. Fig. 3 is a planview of the same, partly in section, through the line mm, Fig. 2.

The object of this invention is to effect the removal of deep snow fromrailroad-tracks in a speedy and economical manner.

Arepresents the frame of the snow-plow, which is made triangular atbottom and top, and with its top much smaller than its base, so that theforward edge and the sides will incline upward and inward. The frame Acan be made of wood or iron, and must be of sufficient strength towithstand the pressure of the snow. The inclined sides of the frame Aare covered with boiler-iron B, and to the said boiler-iron B aresecured, by metal straps or other suitable means, coils of steam-pipe 0,two inches (more or less) in diameter, and of sufficient strength toresist a steam-pressure.

of two hundred pounds (more or less) to the square inch. The pipes O areplaced close together, and are made in sections, the upper end of thepipe of each section being connected with the steam-space of a boiler,D, by a pipe, E, so that steam can be sent through all the pipes or onlythrough the lower sections, as the depth of the snow may require. Theforward bends of the horizontal pipes G are formed of bent couplings H,to prevent the said pipes from being weakened by being bent. Thecouplings H lie close together and add to the strength of the nose ofthe plow, and render it less liable to be injured by striking againstice or other solid obstructions. The pipes G are covered and protectedby a casing, F, of sheetiron, secured to the inner plates, B, by boltsor rivets. The plow is mounted upon trucks G in such a manner-that itsbase may be about two inches above the track.

The steam can be supplied by a boiler, D, placed within the plow, or bythe boiler of a locomotive. In the latter case a second loco motive willbe required to push the snow-plow forward. When the boiler D is placedwithin the snow-plow water-tanks and receptacles for fuel should also beplaced within the said plow for convenience in keeping up a supply ofsteam.

The pipes E should be supplied with cocks, so that the passage of thesteam can be controlled as may be required.

With this construction the surface of the plow in contact with the snowwill be kept hot, so that the snow will slide off the said surfacefreely, and will be more or less melted, so as to pack and remain inplace when thrown from the track.

I am aware that it is not new to use horizontal steam-pipes connected infront by return- N bends, and arranged in planes parallel to each otherand to the track, or to use a double casing divided into channels forthe reception of steam; but D What Icelaim as new andof my invention1s 1. A snow-plow constructed substantially as herein shown anddescribed, consisting of the frame, the inner iron plates, the coils ofsteam-pipes, and the outer sheet-iron casing, as set forth.

2. In a snow-plow, the combination, with the trucks G and the boiler D,of the frame A, the inner iron plates, B, the coils of steam-pipe O, andthe outer sheet-iron casing, F, substantially as herein shown anddescribed, whereby the surface of the plowin contact with the snow willbe kept hot, as set forth.
